Syrian civil war: Why are they fighting in Syria?

The United States launched a cruise missile attack on a Syrian air base Thursday in retaliation for Syria’s use of banned chemical weapons that killed at least 75 civilians.

President Donald Trump, in a speech Thursday from his estate in Florida, said it was clear that Syrian President Bashar al-Assad “choked out the lives of helpless men, women and children,” and that the attack was “in the vital national security interest of the United States to prevent and deter the spread and use of deadly chemical weapons,” Trump said.
